The piepomagnetic property of Fe7 1 .5 Cu1 Nb3 Si1 3 .5 B9 V2 amorphous and nanocrystalline strips by differ-ent annealing process has been studied,and analysed the piezomagnetic property of Fe7 1 .5 Cu1 Nb3 Si1 3 .5 B9 V2 with different composition.The study shows that when the test frequency was 1 kHz and the compressive stressσwas no more than 0.2 MPa,the amorphous magnetic material of Fe7 1 .5 Cu1 Nb3 Si1 3 .5 B9 V2 has excellent piezomag-netic property that the inductance value of amorphous alloy strip closed circuit grows with the increase of the stress applied to the surface of the strip.When the annealing temperature was 550 ℃,stability of the piezomag-netic property of the strip became the best,there was a clarify linear relationship between coil inductance value and time,SI (%)and compressive stress applied to the surface.While the thermal treatment process has a great influence on the piezomagnetic property of Fe7 1 .5 Cu1 Nb3 Si1 3 .5 B9 V2 ,the maximum value of SI (%)would reach to 0.18330 when the annealing process was heating 300 ℃ for 30 min.In addition,the piezomagnetic effect of the strip was related to its composition,in the same testing cases,Fe73 .5 Cu1 Nb3 Si1 3 .5 B9 strips has the best piezo-magnetic effect,followed by Fe78 Si9 B1 3 ,and the piezomagnetic effect of Fe7 1 .5 Cu1 Nb3 Si1 3 .5 B9 V2 was worst.
